If the Covenant tried to Invade Destiny's Earth: Hundreds of Guardian Ships deployed into battle. Fallen Ketches go into orbit (Covenant's existance threatens their great machine) Covenant Drop Pods onto earth Fight wave after wave of fallen as they drop their spider tanks and pikes down. Elite Vs Captain Hive Join in Shriekers start melting through Covenant troops Hunters deployed Ogres Deployed Hive summon an Ascendant The remainder covenant are then bombed by Rasputin Then, the surviving covenant face us, the guardians. Elites try. Sunbreaker hammer clinks. Elites flee. Rest of the Covenant fleet flees. Attacked by cabal and vex ground support on Mars (as seen on bastion) Then when they pass by the cabal, they meet the awoken fleet. If they survive the awoken fleet, they then face oryx's Dreadnaught. Taken spawn in covenant ships. Covenant try to push out of our system, but the Prophets get one final message. A voice is heard over their comms. "Dismantle Mines, yes?"
